Common questions
What is a wrist pin bushing and why is it important?
The wrist pin bushing is a bearing surface located in the small end of the connecting rod, allowing the wrist pin to pivot freely as the piston moves. It's critical for reducing friction and wear between the connecting rod and piston, ensuring smooth engine operation.
Will this wrist pin bushing fit my 2005-2014 Twin Cam Harley?
Yes, this KPMI wrist pin bushing is specifically engineered for Twin Cam engines within the 2005-2014 model range. If your motorcycle predates 2005 or is a Milwaukee-Eight platform, it will require a different part. Always use the Shop by Bike feature to confirm fitment for your exact model.
Is special tooling required for installation?
Installing wrist pin bushings typically requires specialized tools, such as a bushing driver and reamer, to ensure proper fitment and alignment. We recommend professional installation or performing the work with the correct tools and expertise.
